PURPOSE: A drive device for a blade of a gas discharge stack is provided to prevent damage to a casing and a blade by controlling the rotation of the blade and to prevent high-temperature gas from flowing to a heat exchange apparatus. CONSTITUTION: A drive device for a blade of a gas discharge stack comprises a casing(3), first and second rotary shafts(10,20), first and second blades(30,40), first and second turning levers(50,70), and a first link(80). The first and second rotary shafts are installed at the casing. The first and second blades are fixed to the first and second rotary shafts. The first turning lever has a first rotary shaft coupling unit and a first extension unit, and the second turning lever has a second rotary shaft coupling unit and second and third extension units. The first rotary shaft coupling unit is coupled to one end of the first rotary shaft. The first link connects the first and second extension units. When the first rotary shaft is rotated, the first link rotates the second rotary shaft in an opposite direction.
